Interests: Activities which maximise the opportunity for self-directed learning: low floor, wide walls and high ceiling with particular emphasis on the walls and ceiling. My Sugar favourites: Turtleart, Scratch, Etoys. Game Maker still my Windows favourite.
Currently user testing Turtleart and Sliderule, experimenting with Pippy. Supporting the Timor Leste deployment.
Preschool student Activities, some links
Radia Perlman in the 70s when at student at MIT did extensive experiments with preliterate children and the LOGO turtle and built a number of interfaces for them. She also spent some time at Xerox PARC and did many similar experiments with chldren 3 years on up.

http://alumni.media.mit.edu/~mcnerney/personal-ubicomp.pdf more discussion than the above
Turtle Art - text free
To what extent could pre-literate children use Turtle Art?
Are graphics on blocks really better than text?
Does keeping text labels help develop literacy?
What graphics are best?
Some features, eg. the heap are unlikely to be used by pre-literate children, should they be omitted or retained with text labels?
The following graphic is a discussion starter
or another [suggested layout]]

Sea Surface Temperature Mapping
Sea surface temperature mapping, inspired by http://oceanpc.org . Described here is a program to read and display the temperature data which is available at http://www.ncdc.noaa.gov/oa/climate/research/sst/sst.html
The data format is described at ftp://eclipse.ncdc.noaa.gov/pub/ersstv3b/README
The first record in the file ersst_v3b_2010_2019.asc , the 2010 to 2019 data set, reads:
-9999 -9999 -9999 -9999 -9999 -9999 -9999 -9999 -9999 -9999 -19 13 18 11 7 25 64 132 255 427 607 791 990 1198 1408 1616 1816 1999 2149 2258 2327 2360 2365 2355 2347 2359 2393 2443 2500 2568 2654 2736 2789 2826 2869 2904 2911 2903 -9999 -9999 -9999 -9999 -9999 -9999 -9999 -9999 -9999 -9999 -9999 -9999 -9999 -9999 -9999 1489 1432 -9999 -9999 -9999 -9999 -9999 713 -9999 656 715 780 796 744 669 596 476 298 156 113 70 -134 -180 -180 -180 -180
-9999 represents land, the other numbers are degrees C x100 This record represents a line running from the south pole through to the north pole in 2 degree increments at longtitude 0 for the first month and year. The next record is for lattitude 2 degrees east and so on.
Sample Pippy(Python) program
This Pippy(Python) mapping program is supplied as a starter and as inspiration for further investigation
File:Write Activity sst.odt Pippy code as open office doc. Download and open in Journal. Copy from the Write session, paste into Pippy and run.
Alternatively download this content bundle File:Sst.xol to the journal, starting the bundle from the journal installs the bundle as off line web content which is accessible from the Browse home page as sst in the Science category. This content includes the Python source and a sample data file.
Challenges
- Display the other months and years in the file
- Display the month and year in the title bar
- Animate the display
- Do a legend
- Display the temperature at the cursor
- Map other data
- Error checking
- Display partly corrupted data sets without crashing
- Create models of ocean or atmosphere
- More ideas at http://oceanpc.org , http://marinedataliteracy.org/index.html and http://data.worldbank.org/
(This program has also been done in Game Maker on the Windows OS)
